摘要： An ink is provided, which includes a resin, UV curable monomer, and photo initiator. The resin is formed by reacting a plurality of end capping agents with a dendrimer compound in an environment including esterification catalyst, inhibitor, and first solvent. The dendrimer compound is formed by reacting a multi-hydroxy compound and a plurality of hydroxy-containing epoxy compounds in an environment including alkaline catalyst and second solvent. The multi-hydroxy compound and the hydroxy-containing epoxy compounds have a molar ratio of 1:6 to 1:20, and the multi-hydroxy compound and the end capping agents have a molar ratio of 1:6 to 1:20. The end capping agents include acrylic acid, methacrylic acid, glycidyl methacrylate, or 2-amino acrylic acid. The resin and the UV curable monomer have a weight ratio of 100:30 to 100:5000, and the resin and the photo initiator have a weight ratio of 100:30 to 100:500.

摘要： A method of preparing fiber includes blending bio-compatible ceramic powder and first polyester to form a ceramic powder composition, wherein the bio-compatible ceramic powder and the first polyester have a weight ratio of 10:90 to 60:40. The method further includes blending the ceramic powder composition and second polyester to form a composite material, wherein the ceramic powder composition and the second polyester have a weight ratio of 0.4:99.6 to 40:60. The method also spins the composite material to form a fiber. The first polyester has an intrinsic viscosity (IV) of 0.35 dL/g to 0.55 dL/g, and the second polyester has an intrinsic viscosity (IV) of 0.6 dL/g to 0.8 g/dL. The fiber can be woven to form an artificial ligament/tendon.
